Be wary of names. 'junk' DNA is not rubbish ... it's called 'junk' because we don't know entirely what it is used for... But just look at all the blank spaces on this post. They are nothing, but they are keeping the words in order.   Evolutionaries are putting too much faith in names of words - such as human embryonic 'gill slits'   or   'transitional' fossil
